In this paper, poly-m-phenylene isophthalamide (PMIA) staple fibers were dissolved in a LiCl/N,N-dimethylacetamide solvent system in order to prepare PMIA nanofibers via the electrospinning method. The mean diameter of the nanofiber was between 72 and 247 nm and gradually increased with increasing LiCl concentration PMIA nanofibers were characterized by SEM, Fourier transform IR spectrometry, a thermogravimetric analyzer and Brunauer-Emmett-Teller anal. Besides, the tensile strength of PMIA nanofiber yarns was tested and analyzed, combining the orthogonal array method. The results showed that the diameter and uniformity of nanofibers decreased gradually with increasing PMIA and LiCl solution concentration The thermal properties, the sp. surface area and chem. structures of PMIA nanofibers were improved comparing with PMIA stable fiber. It was found out that the LiCl concentration could influence the interactions among polymer mols. and caused the fibrils to wrap around each other, forming fiber clusters. The LiCl concentration was the most important factor affecting the tensile strength of PMIA nanofiber yarn. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Safety of Lithium chloride).
Lithium chloride (cas: 7447-41-8) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.Safety of Lithium chloride
